< p > This task checks xml files are valid (or only well formed). The
2002-04-22 08:56:13 +00:00
task uses the SAX2 parser implementation provided by JAXP by default
2002-09-09 16:49:23 +00:00
(probably the one that is used by Ant itself), but one can specify any
SAX1/2 parser if needed.< / p >

< li / > < tt > < dtd> < / tt > elements which are used to resolve DTDs and entities.

These can be any number of < a href = "http://www.saxproject.org/apidoc/org/xml/sax/package-summary.html#package_description" > http://xml.org/sax/features/< / a > or other features that your parser may support.

< p > The attribute element is used to set SAX Parser features.
There can an arbitrary amount of attribute set as defined here:
< a href = "http://www.saxproject.org/apidoc/org/xml/sax/package-summary.html#package_description" > http://xml.org/sax/features/< / a >
A feature essentialy changes the mode of the parser.
< attribute> an attribute is used to set specific features on the parser.
